Electrons orbit around the nucleus of an atom, forming what is known as an electron cloud. The nucleus contains protons and neutrons, which are bound together by the strong nuclear force. Protons, positively charged particles, determine the atomic number and identity of the element, while neutrons, which are neutral, contribute to the mass of the atom but do not participate in electrical interactions.

Electrons, in contrast, are negatively charged particles that exist in various energy levels or shells around the nucleus. This arrangement allows for the stability of the atom, as the attraction between the negatively charged electrons and the positively charged protons helps keep the electrons in their respective orbits. The distribution and behavior of these electrons are fundamental to chemical bonding and reactivity.

Photons are particles of light and do not have a role in the atomic structure in terms of orbiting around the nucleus. They can interact with electrons, but they are not constituents of the atom. Thus, the presence of electrons as orbiting particles is a defining characteristic of atomic structure.
